CAPE CANAVERAL AIR FORCE STATION, FL – The second round of March Launch Madness continued with the thunderous nighttime blastoff of a ULA Delta IV rocket powering a super swift military communications satellite to orbit in a collaborative effort of U.S. Allies from North America, Europe and Asia and the U.S. Air Force.

The next generation Wideband Global SATCOM-9 (WGS-9) military comsat mission for the U.S. Force lifted off atop a United Launch Alliance (ULA) Delta IV from Space Launch Complex-37 (SLC-37) on Saturday, March 18 at 8:18 p.m. EDT at Cape Canaveral Air Force Station, Florida.

Check out this expanding gallery of spectacular launch photos and videos gathered from my space journalist colleagues, myself and spectators ringing the space coast under crystal clear early evening skies.

A key feature in this advanced Block II series WGS satellite is inclusion of the upgraded digital channelizer that nearly doubles the available bandwidth of earlier satellites in the series.

WGS-9 can filter and downlink up to 8.088 GHz of bandwidth compared to 4.410 GHz for earlier WGS satellites. It supports communications links in the X-band and Ka-band spectra.

Note that Round 3 of March Launch Madness is tentatively slated for March 29 with the SpaceX liftoff of the first ever reused Falcon 9 first stage from historic pad 39 on NASA’s Kennedy Space Center.

The WGS-9 satellite was paid for by a six nation consortium that includes Canada, Denmark, Luxembourg, the Netherlands, New Zealand and the United States. It joins 8 earlier WGS satellites already in orbit.

The partnership was created back in 2012 when the ‘WGS-9 Memorandum of Understanding (MOU)’ was signed by Defense organizations of the six countries.

The WGS-9 MOU agreement to fund the satellite enabled the expansion of the WGS system with this additional satellite added to the existing WGS constellation.

“The agreement provides all signatories with assured access to global wideband satellite communications for military use,” according to the US Air Force.

WGS-9 was built by Boeing.

The 217 foot tall Delta IV Medium+ rocket launched in the 5,4 configuration with a 5 meter diameter payload fairing that stands 47 feet tall, and 4 solid rocket boosters to augment the first stage thrust of the single common core booster.

The payload fairing was emblazoned with decals commemorating the 70th anniversary of the USAF, as well as Air Force, mission and ULA logos.

Orbital ATK manufactures the four solid rocket motors. The Delta IV common booster core was powered by an RS-68A liquid hydrogen/liquid oxygen engine producing 705,250 pounds of thrust at sea level.
A single RL10B-2 liquid hydrogen/liquid oxygen engine powered the second stage, known as the Delta Cryogenic Second Stage (DCSS).

The booster and upper stage engines are both built by Aerojet Rocketdyne. ULA constructed the Delta IV Medium+ (5,4) launch vehicle in Decatur, Alabama.

The DCSS will also serve as the upper stage for the maiden launch of NASA heavy lift SLS booster on the SLS-1 launch slated for late 2018. That DCSS/SLS-1 upper stage just arrived at the Cape last week – as I witnessed and reported here.

Saturday’s launch marks ULA’s 3rd launch in 2017 and the 118th successful launch since the company was formed in December 2006 as a joint venture between Boeing and Lockheed Martin.

CAPE CANAVERAL AIR FORCE STATION, FL – On the 70th anniversary year commemorating the United States Air Force, a ULA Delta IV rocket put on a daunting display of nighttime rocket fire power shortly after sunset Saturday, March 19 – powering a high speed military communications satellite to orbit that will significantly enhance the targeting firepower of forces in the field; and was funded in collaboration with America’s strategic allies.

The next generation Wideband Global SATCOM-9 (WGS-9) military comsat mission for the U.S. Force lifted off atop a United Launch Alliance (ULA) Delta IV from Space Launch Complex-37 (SLC-37) on Saturday, March 18 at 8:18 p.m. EDT at Cape Canaveral Air Force Station, Florida.

The launch and separation of the payload form the Delta upper stage was “fully successful,” said Major General David D. Thompson, Vice Commander Air Force Space Command, Peterson Air Force Base, CO, to our media gaggle soon after launch at the press view site on base.

“The WGS-9 mission is key event celebrating the 70th anniversary of the U.S. Air Force as a separate service. The USAF was created two years after World War II ended.”

It is the ninth satellite in the WGS constellation that serves as the backbone of the U.S. military’s global satellite communications.

“WGS provides flexible, high-capacity communications for the Nation’s warfighters through procurement and operation of the satellite constellation and the associated control systems,” according to the U.S. Air Force.

“WGS provides worldwide flexible, high data rate and long haul communications for marines, soldiers, sailors, airmen, the White House Communication Agency, the US State Department, international partners, and other special users.”

WGS-9 also counts as the second of at least a trio of launches from the Cape this March – with the possibility for a grand slam fourth at month’s end – if all goes well with another SpaceX Falcon 9 launch from pad 39A.

The is the seventh flight in the Medium+ (5,4) configuration; all of which were for prior WGS missions.

CAPE CANAVERAL AIR FORCE STATION, FL – As sunset dawns on the venerable Delta rocket program, the sole Delta slated to launch from the Cape this year is set to dazzle at sunset tonight, Saturday, March 18.

And the launch site is drenched with brilliant blue skies this afternoon as I watched the Delta rocket exposed to the heavens as the mobile service tower rolled away from on site at pad 37.

Florida’s Space Coast will light up with a spectacular sunset burst of fire and fury as a United Launch Alliance (ULA) Delta rocket roars to space with a super advanced tactical satcom for the U.S. Air Force that will provide a huge increase in communications bandwidth for American forces around the globe.

Blastoff of the Wideband Global SATCOM (WGS-9) mission for the U.S. Air Force is slated for 7:44 p.m. EDT on Saturday, Mar. 18, 2017 from Space Launch Complex-37 at Cape Canaveral Air Force Station, Florida.

So it’s past time to ‘get your ass to the Cape’ – because the weather is glorious in central Florida. And … a Atlas rocket is slated to launch in only five or six days – late next week! in six next Friday.

It is the ninth satellite in the WGS constellation that serves as the backbone of the U.S. military’s global satellite communications.

“WGS provides flexible, high-capacity communications for the Nation’s warfighters through procurement and operation of the satellite constellation and the associated control systems,” according to the U.S. Air Force.
